Sulphuric Acid Apparatus.

the strongest acid, called oil of vitriol, sp. gr. 1.85. Chamber acid reaches sp. gr. 1.5 and tower acid 1.65.

Fuming sulphuric acid, H„S,0,, sp. gr. 1.9, solid at 0° C, fumes in the air and is very corrosive. It was known in the 15th century. This is made in Bohemia by oxidizing pyrites ■contained in slate by exposure to moist air to iron persulphate and distilling the product in clay flasks, the acid passing off. It is also made by Winkler's process by passing sulphur dioxide and oxygen over platinized asbestos, where it is oxidized to sulphur trioxide, which is dissolved in sulphuric acid. This ucid is used for dissolving indigo, and in the manufacture of aniline and anthracene dyes.

It combines with water with violence to form sulphuric acid. It acts energetically as a dehydrating agent.

Sulphuryl Chloride. SOaCI3. Liquid, easily decomposed by water; made by the action of chlorine on sulphur dioxide in direct sunlight.

Its earliest form was Campbell's burning lens recorder: at present various forms of photographic or blue-print records are more generally adopted, as those of Stokes, Jordan, and Curtis.

latitude 5° and 45°. Occasionally a spot is large enough to be visible to the naked eye. The duration may be only a few

Sunstroke. Condition produced by exposure to excessive heat. There are two forms: (1) Heat exhaustion and (2) Heat stroke. 1. Prolonged exposure to high temperature, especially when combined with physical exertion, is apt to be followed by extreme prostration, collapse, and, in severe cases, delirium. The surface is usually cool, the pulse small, rapid and soft; the breathing easy though hurried; the temperature may be less than normal; while the vital forces fall into a collapse, the senses remain active. The individual need not be exposed to the direct rays of the sun. but the condition may come on when working in close, confined rooms during midsummer, or even be produced by artificial heat, as in the boiler room of an ocean steamship. The treatment includes the use of stimulants, ammonia is frequently valuable, and, whatever stimulant is used, it may be necessary to use it liyperdermically. When the temperature is below normal, a hot bath is indicated. 2. Heat stroke, thermic fever. This chiefly occurs in persons working very hard and exposed to the sun, especially if thny have been drinking beer or whisky. There is unconsciousness with hitrh temperature and the indications of a febrile condition. The indications for treatment are to reduce the temperature as rapidly as possible. Place the patient in a bath of the temperature of 70° F., use an ice pack, or rub the body with ice.

This takes place by fragmentation of the female nucleus and the consequent formation of as many embryos as there are zygotes. The result is monstrous and abortive development.

Superheated Steam. Steam at a higher sensible temperature than that which corresponds to its boiling-point at that pressure (see Saturated Steam). It is used in engines, so that the heat lost by internal condensation in the cylinder may be supplied from the incoming steam without condensation. The water or mist from such condensation would be reevaporated when the pressure was lowered by expansion of the steam after cut-off; for such evaporation additional demand for heat is made, which new steam and the hot cylinder walls must supply, and so on at each stroke.

Superior Limit Op Integration. That toward which the definite integral is reckoned. When the limits are indicated, it is placed at the upper, the inferior at the lower extremity of the sign of integration.

Superior Limit op Roots. Quantity larger than the largest root. The ordinary limit is found by subjecting the largest negative coefficient to the root indicated by the position of the first negative coefficient from the first term: the result increased by one is the superior limit. The least superior limit is found by Sturm's theorem as a basis for approximating to the incommensurable roots.

See Calcium Phosphates.

Supersnturation. Some solutions have a higher coefficient of solubility when hot than when cold. If such a hot saturated solution be carefully cooled, the salt does not immediately crystallize, but the liquid remains in a condition of supersaturation, and is in a state of unstable molecular equilibrium. If a crystal of the same salt be dropped in, the excess held in solution immediately crystallizes.

If, when cold, a crystal of the salt be brought in contact with the fluid, the mass instantly solidifies with the evolution of heat.

Surgeons, College Of. Originated from 1460-61, and after various stages became the Royal Coll. of Surgeons of London in 1800. Its museum is the finest of its kind in Gt. Britain. Surgery. Originally a branch of medicine involving the

employment of manual operations. The term has been widened on the one hand to include more than this, and limited by the specialties on the other, making it difficult to draw a sharp dividing line. It may be considered to be that branch of medicine which takes cognizance of the diseases and accidents of those parts of the body that can be directly inspected, and the operative care of those parts that cannot be. Some Surgical Instruments from Pompeii. writers do not use the term so comprehensively, as they exclude the specialties. Surinam. Name given to Dutch Guiana. See Guiana. Surinam Toad. See Aolossa.

Surplus Produce Of Land. Produce in excess of the amount which would have just recompensed the cultivator for his expenditure of labor and capital.

Surprise. In its simplest form, feeling aroused by a sudden, unexpected presentation. It seems to depend on a lack of harmony between the presentation and the expectant attention. This produces apparently a sort of mental shock, in its essence disagreeable. The characteristic facial expression of surprise, viz., intensified attention, is a preservative reaction, whose function is to obtain a clearer presentation of the object causing the feeling. Should the object continue strange and unrecognized, the feeling passes into wonder, which is a state much more intellectual and complex.

Survivorship. Whether A outlives B is to be established, under English law, by evidence, and not by presumptions based on age, sex, or physical strength.
